“…Studies of learning and instruction indicate that students learn more when explaining examples to themselves (Chi, Bassok, Lewis, Reimann, & Glaser, 1989;VanLehn & Jones, 1993), and justifying one's reasoning has been shown to facilitate problem-solving performance, at least under some conditions (Ahlum-Heath & Di Vesta, 1986;Gagne & Smith, 1962;McGeorge & Burton, 1989;Stinessen;1985).
